Thanks FallernJehova.
I have already gone through the article, and this is what is has to
say about blank:
"blank validates that a field is blank or contains only whitespace
characters like tabs or spaces. It doesn't look very useful to me."
I know what it does, but what I wanted to know was any
situation/example where using it will be useful. One use that came to
my mind was checking that the id field is empty (if present) when
adding a new record. (Of course there are other ways to this):
var $validate = array(
'id' => array(
'rule' => 'blank',
'on' => 'create'
)
);
Any other situation, where using the blank may be useful?
Thanks
